Oh well. Don't say you've not been told it might not work very well.
It seems (only spotted this today) that the Digital Economy Act (rushed through as it was up for debate on the day the date of the election was announced, so went through "on the nod" with few changes and very little scrutiny) has provisions which could allow for blocking of file sharing sites (as protection of intellectual property), but their effectiveness is under the microscope.
On Feb 1st, the Government asked Ofcom to review the provisions for blocking, in part to see if they are achievable, so there is clearly some doubt. Here are the questions for Ofcom:
1 Is it possible for access to the site to be blocked by internet service providers?
2 How robust would such a block be ? in other words would it have the intended effect, and how easy would it be to circumvent for most site operators?
3 What measures might be adopted by internet service providers to prevent such circumvention?
4 How granular can blocking be ? i.e. can specific parts of the site be blocked, how precise can this be, and how effective?
5 How effective are sections 17 and 18 of the Act in providing for an appropriate method of generating lists of sites to be blocked?
6 If possible, identify either a potential range of costs for ISP blocking solutions or the main drivers of those costs.
You can see from items 1 to 3 that bypassing a block is giving someone sleepless nights, as it would look pathetic if the law was made but could do nothing to prevent easy avoidance.
There was speculation that the attempts to close down Wikileaks, where some powerful government bodies acted together but failed, has shown how similar attempts to block file sharing and porn could be a 'cat and mouse' game with the authorities always a few steps behind.
I know the DEA is a separate issue, but it has broadly similar blocking requirements.
